Making a Leather Rolled Handle or Loop for a Bag

I have been asked to explain in a bit of detail how to make a rolled handle, I have an opportunity to do a rolled loop and up to a point, the process is the same. You can adjust the length or diameter of the handle to suit your needs, but the process remains the same. I thought it better to add something rather than leave it till I get a chance for a rolled handle video. I hope it helps a little.
